To all whom it may concern:

Be it known that I, PAonYnso, a citizenof Czecho-Slovakia, residing at Dodgeville in the county of Houghton and State Michigan, have invented certain new and useful Improvements in Flying-Machines,

. of which the following is a specification.

The present invention has particular reference to a flying machine wherein the occupant of the machine is in control of the manually operated mechanism for causing the rise and fall of the machine.

A further object of the invention resides in the provision of a flying machine embody ing a horizontally positioned helicopter propeller that is manually operated for elevating the machine while a shiftable weight is supported on the 'machine for counterbalancing the same to assume a vertical position and also adapted to be shlfted to cause the desired inclination of the machine as in an upwardly inclined controlling movement or in volplaning. I

With the above and other objects in view, the present invention consists in the novel form, combination and arrangement of parts hereinafter more fully described and shown in the accompanying drawing wherein likereference characters indicate similar parts throughout the several views.

In the drawings, V

Figure l is a side elevational view of a flying machine constructed in accordance with the present invention-showing the seat and supporting bracket therefor in collapsed dotted line position,

Fig. 2 is a rear elevational view thereof showing the chain and gear mechanism for operating the propeller screw,

Fig. 3 is a horizontal sectional view taken on line III-III of Fig. 1 carrying the chain and sprocket mechanism forshifting the counterbalancing weight,

Fig. 4 is a detail sectional view of a portion of the supporting frame showing the supporting brace for the seat frame,

Fig. 5 is a fragmentary sectional view. of the upper end of the flying machine,

Fig. 6 is a horizontal sectional view taken on line VI--VI of Fig. 1 showing the supporting feet for the lower end of the machine frame, and

. Fig. 7 is a fragmentary sectional view showing the counterbalancing weight supported on the shifting chain therefor.

Referring more in detail to the acoom- I Specification-of Letters Patent.

panying drawings, there is illustrated a flying machine designed for manual operation and for carrying a single person and embodies a vertical tubular standard 1 provided at the lower end thereof with radial feet 2 for supporting the same in vertical position when inactive. The seat supporting frame is more clearly shown in Figs. 1, 4, and 6 as embodying an arm 3 pivoted at one end to the lug 4 carried by the vertical standard 1 while aseat 5 is carried by the other end of'the arm. In order to hold the arm 3 and seat 5 horizontallypositioned as shown by full lines, a brace rod 6 is pivoted as at 7 to the outer end. of the arm 3 and is forked at its other end as at 8 for strad-- dling the U-shaped bracket 9 carried by the standard lat a point below the projecting lug 4. and in vertical alinement therewith. It will therefore be seen that with the brace rod 6 engaging the U-shaped bracket 9, the

arm 3 and seat 5 are horizontally positioned for carrying a passenger.

A shiftable counterbalancing weight is supported on the standard 1 andis more clearly shown in Figs. 1, 3, 4, and 7 and while sprocket chains 16 pass over the sprocket wheels 13 and 15. A pedal crank 17 is associated with the bearing shaft 14 to effect a lifting movement of the sprocket chain 16. The counterbalancing weight embodies a plurality of plates 18 of desired material that are supported on screws 19 having plate supporting nuts 20 upon the lower ends thereof while the upper ends of the screws are provided with hooks 21 for engagement with the rods 22 extending between the lower sections of the chain 16. It will therefore be observed that a person riding upon the seat 5 is in absolute control of the shifting weight 18 with the feet resting upon the crank arms 17 ,and by operating the crank arms in either direction, the

of the person upon the seat or for conor descending.

the weight 18,

' A helicoptlcal propeller is mounted upon the upper end 0 the standard 1 and embodies a hub 23 having an integral beveled ear 24 at its lower end, the hub and gear avin a central openin journaled upon the upri t 25 secured to t e upper end of the standard 1 and resting upon the bushing 26 fixed to the upper end of the standard. Screw propeller blades 27 project in horizontal directions from the hub 23 and at points intermediate the ends thereof are connected to guy wires 28 that are connected at their upper ends as shown in Fig. 5 to a disk 29 having a central opening received on the pin 30 at the upper end of the upright 25. The driving mechanism for the screw propeller embodies a shaft 31 journaled transversely of the upper end of the upright 1 .and carrying upon one end thereof a beveled gear 32 that is in constant mesh with the beveled gear 24, the other end of the shaft 31 carrying a sprocket wheel 33 over which a sprocket chain 34 passes, while the lower portion of the endless sprocket chain 34 engages the sprocket wheel 35 secured to the shaft 36 journaled transversely of the upright 1 at a point adjacent the seat 5 while hand cranks 37 are associated with the shaft 36 to effect a rotation thereof.

In the operation of the device, assuming that the seat arm 3 is in the full line position shown in Fig. 1, and with a person upon the seat 5, the pedals 17 may be operated to shift roperly to counterbalance the machine. l 3y operating the handle cranks 34, power is communicated to the screw propeller hub 23 sufliciently to elevate the machine from the ground, the elevation of which is controlled by the speed of rotation. Forward travel, of the machine may be obtained by shifting the counterbalancing weight 18 to cause a forward inclination of the standard 1 with the result that the machine will be given a volplaning action, and by restorin the weight to its initial position, the stan ard .1 may be vertically disposed and the machine caused either to ascombination and arrangement of parts with-' out departing from the spirit and scope of the invention as hereinafter claimed.

What is claimed as new is:

1. A flying machine of the type'described comprising a vertical standard, a seat frame supported thereon, a counterbalancing weight shiftably mounted on said standard in directions at right angles to the longitudinal axis thereof, a helicoptical propeller j ournaled upon the upper end of said standard, manually operating means for said propeller, said counterbalancing Wei ht including an endless chain device an a weight supported on said chain. I

2. A flying machine of the t pe described comprising a vertical stan ard, a seat frame supported thereon, a counterbalancing weight shiftably mounted on said standard in directions at right angles to the longitudinal axis thereof, a helicoptical propeller journaled upon the upper end of said standard, manually operatingmeans for said propeller, said operating means includin meshmg gears and chain and sprocket mec anism for operating said gears.

3. flying machme of the type described comprising a vertical standard, a seat frame supported thereon, a counterbalancing weight shiftably mounted on said standard in directions at right angles to the longitudinal axis thereof, a helicoptical propeller journaled upon the upper end of said stand ard, manually operating means for said propeller, said operating mechanism including a hub for the propeller, a beveled ar inte gral with said hub, a beveled gear Journaled on said standard in mesh with the hub gear and chain and sprocket mechanism for operating said gears.

In testimony whereof I afiix my signature.
